IMPROVEMENT IN TRANSOMS FOR DOORS,

Specification forming part of Letters Patent No. 164,794, dated June 22,1875; application filed May 18, 1875. a

To allwhom it may concern:

Be it known that I, JOHN BERNDT, of Denver, in the county of Arapahoe,and Territory of Colorado, have invented a new and Improved Transom forDoors; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the accompanyingdrawing, forming a part of this specification, in which-- Figure 1 is avertical side elevation with parts broken away Fig. 2, details of thefastening device.

This invention relates to cetain improvements in transoms for doors; andit consists in a transom-sash that is made to slide into a casing above,by means of a' branched cord moving Over pulleys, one of the branches ofwhich cord is attached to the sash for the purpose of raising it, andthe other attached to a suspended detent or locking-bar, which preventsthe raising of the sash except by the cord upon the inside of the house,the cord being fastened below by a self-closing cam-lever, and soarranged at its branched ends, as to raise the sash and lift thelockingbar away at the same time.

In the drawing, A represents the sash of the transom, having groovesupon its edges which receive and slide over tongues attached to theframe B, to exclude dust, snow, and wind. 0 is a casing or chamber abovethe transom, into which the transom-sash slides when raised. 1) is acord, which passes over pulleys E E E in the casing, and is attached tothe top part of the transom-sash at one end, and is fastened at aconvenient distance below by a self-acting device, F. Said deviceconsists of a frame, a, and a lever, b, having a serrated or ridged camedge, which presses against the cord from the weight of the lever, andholds the said cord at any adjustment. G is a branch cord, attached tocord D at one end, and at the other end to a swing detent orlocking-bar, H. This locking-bar serves to hold the sash down, and actsas a safetycatch to prevent entrance from the outside by burglars, thebar being so arranged as to be removed from its locking position only bya traction upon the cord upon the inside.

By means of this improved construction and arrangement of parts, thetransom may be readily adjusted at any height for ventilation, the sashautomatically locked, when closed or down, and all dust, snow, 850.,excluded.

Having thus described my invention, what I claim as new is'- Thetransomsash A, in combination with the casing O, the cord D, pulleys E EE fastening F, branch cord G, and the locking-bar H, substantially asand for the purpose described.
